Abstract
An image processing device used for a projector displays an image by projecting the image on a projection surface. A detection image generation section adapted to generate a detection image, which is an image adapted to detect a state of a projection image displayed on the projection surface, and includes a plurality of detection image parts is provided. Each of the detection image parts includes a plurality of regions having respective luminance values different from each other. The detection image generation section changes the luminance distribution of each of the detection image parts of the detection image to be generated so that the maximum luminance values of the detection image parts included in the taken detection image obtained by taking the detection image projected on the projection surface fall within an allowable range.
